D = 28m[325o]CCW + 45m[270o]CCW.
X = 28*Cos325 + 45*Cos270 = 22.9 + 0 = 22.9 m.
Y = 28*sin325 - 45*sin270 = -16.1 - 45 = -61.1 m.
Q4.
Tan A = Y/X = -61.1/22.9 = -2.66812.
A = -69.5o = [E69.5oS] = 290.5 CCW.
D = Y/sin A = -61.5/sin290.5 = 65.2 m.
V = D/T = 65.2m/6.9s = 9.5 m/s.[E69.5o]
A car travels 28 m [E 35° S] and then turns and travels 45 m [S]. the whole motion takes 6.9s.
what is average velocity?
answer: 9.5m/s [E 69° S]
How do i find the displacement to find V if its not a right triangle
